I've been looking forward to your opinion and images from the A7 with the ZM25/2.8. I can't view the full resolution files at work, but at the reduced size it looks very promising. I just picked up my A7 today locally, and brought in some of my glass for the guys at the shop to play with on the camera (they mostly only get their hands on everything except CV, Zeiss, and Leica). Incidentally they said that Sony has provided much better representation with this rollout than past offerings, and that they are expecting pretty frequent shipments to match the greater than expected demand. The guys I spoke with said it's an exciting time to have a brick and mortar shop, with refreshing product lines and an uptick in sales of late.
Ulrikft2,
Is is just me, or is the left side of the image soft compared to the right? I have the same lens, but will be using it on the A7. On my preliminary toying around with the combo, I wasn't able to get crisply sharp edges wide open until around f/4 from up close. Tonight hopefully I can do some more dedicated testing. Anyway, your image reminds me of what I experienced with an adapter on my NEX-6 that must have introduced a slight tilt, to the point I could not reach infinity. The was fixed with a different adapter in my case....Show more →
Yeah, it is most likely an adapter issue, working on shimming it currently!

The main thing I have learned: every test winds up having some procedural flaw that throws its results into question!
So the consensus is that the arc present in the A7r shots is not necessarily indicative of the sensor, but may be an outcome of partial clipping and/or JPG artifacts? But, that said, the consensus is also that there seems to be more color cast in the corners on the A7r with the CV 35 1.2.
Is that fair?
Why dont you open these two links in two tabs and then switch in between. You dont have to click on the images, the "new" look of Flickr should be enough and typically you'll see some 6 miniatures in your screen.
Right from the top it is obvious which cam that has the most color cast. If you dont see it, scroll down (in both tabs) to say the CV15 and/or CV12 images. Order is not exactly the same but you'll easily spot what going on between these cameras.
Then, if you scroll down further you'll see images from the CV35/1.2. You'll be able to spot that there is no obvious color cast in any of the cams compared to the more problematic lenses. So I think you're searching for a problem that isnt there in any practical sense.

Do you know if there's any sample on the CV 21/1.8 with both A7 and A7R like the above links? Thanks!

Funny, but I seem to totally disagree, and I encourage you to take another look!
Offhand, I see more vignetting and color in the A7r -- try bringing both into Lightroom (or whatever) and crank the vibrance -- because I honestly don't understand how that doesn't show a rather meaningful difference in the files...
As it stands, most people here seem to think this doesn't show much, though I don't entirely understand why it doesn't.

Thanks.
The A7R photos seem blown out. I saw those color banding for blown out channel before. So it means it is not the problem of the sensor, it is a wrong exposure (I guess the shooter didn't use the same settings on both cameras too, so that is not a direct comparison of which sensor has better recovery capability)

I think he is saying in practice that doesn't matter. What I saw from those photos is at the worse setting (wide open at infinity) A7R show some color shading for the CV35/1.2 but A7 doesn't. In practice when one shot wide open it is something near, when one shot at infinity they stops down for DOF.
By the way, the CV 12/5.6 on the other hand has a big difference in results from A7 and A7R.

What I see between those two images is that they are shot in two different light levels and two different light colors ... one is in soft cooler overcast and the other in warmer more direct light. Note the specular highlight and shadow variance between captures as well as the color variance in multiple areas of the image.
Making any meaningful color/shading comparison is somewhat mitigated by the different lighting/WB/exposure.

You opened both links, and don't see more vignetting in the A7r?
Did you import them into Lightroom, and not see a meaningful difference between them with Vibrance cranked?
It's odd that it seems to me a striking difference -- but to many of you, there's little/no diff.
I get the "real world" argument -- but I guess I'm seeing it as a "canary in coalmine" case that is now leading me toward A7 (I had been expecting to go A7r).

Hi Matt,
Thanks for your comments. In fact I only received my adapter yesterday so didn't have much time for shooting. The weather is very nice in Thailand so hopefully in the weekend I also heard the same thing from my supplier, that Sony is cranking up the production and in fact my camera arrived 2 weeks early.

Just want to say I see the difference you are talking about and I have to same dilemma if I should get A7 or A7R. Using A7 makes my daily life easier, but using A7R gives me the flexibility to print big.
Right now I lean more towards to A7R since the samples I saw from CV21/1.8 and 35/1.2II only have slight color shading wide open at infinity and otherwise seems fine. I want to see more sample before my final decision though.

It's not that we don't see the difference ... but we also see a reason for the difference that is not relegated to the differences in the cameras, but rather differences in the capture, e.g. different lighting.
p.132 #20 · A7/A7r - performance with WA RF lenses
Why would the somewhat different lighting between pairs of comparative shots consistently result in darker, pinker corners for the A7r -- in photos from two totally different people?
I don't mean for that to sound snarky, I hope it doesn't!
I defer to a ton of amazing expertise here, but my eyes seem to keep telling me a different story?
